AL-C (Relay contact of the Complete load).

Change of the state if the load programmed in the parameter is overcome. AL-S (Relay contact of the Overload).

Change of the state if the load programmed in the parameter is overcome. AL-A (Relay of the Auxiliary).

Change of the state if the load programmed in the parameter is overcome.

Remarks: The state of rest of the relay can change in the parameter of

HOLD (It activate with a tension between 24 & 230 V alternating or continuous). When the elevator is in progress, the measure of the weight is not good.The relay could be activated & the cabin display turns unstable. Activating the entrance of HOLD when the elevator gets in movement.The measure of weight is blocked,then the display presenting in intermittent, & the relay together with the cabin display conserves its state until this entrance is disabled, that should be after stopping the elevator. OUTPUT OF CABIN DISPLAY

It can give two types of output,that which you can select it on the parameter . a) Output that is activated in an intermittent way when an overload takes place. The output has polarity, & it can be valid to activate a led and a buzzer (continuos current 7,5V máx.75mA). b) Activation of progressive display MB-D (Two threads connection without polarity).

3. Keys of access to the parameters of menu’s.

The unit has a menu to accede to the adjustment of the parameters.

Pressing this key successively, will go going to all programmable parameters of the menu in a cycle way. To return to the visual presentation of weight, press the key several time until to arrive at the end of the menu, or just press it during 2 seconds. Remarks: If when entering in the menu appears in intermittent, the unit has set a key and is necessary introduce you keycode in this moment in orden to modify the parameters. Pressing this key enters in the selected option and once inside we will be able to select the digit to modify. Remarks: In the event of not being able to enter, it means that the key is protected. And it is necessary to introduce your keycode.

See section No8 (Auxiliary functions ) Pressing this key will modify the selected digit. Also by pressing this key when you are located on the selected parameter, the display presents its content.

Remarks: The only content that you ́ll not see is the parameter 4. Modification of the parameter

1) Press the key successively until being place on the desired parameter. 2) Press the key to enter in modification of the parameter, being the left digit in intermittent.

3) Put in the display the wanted value, using this keys .

4) Press the key twice to save the assignated value. Then the display will present the next parameter. Remarks: a) If you haven’t press 2 times, the operation will not stored,and the display presents again the parameters that you was modifying.

b) To modify the parameters y , please consult section No.6 (Calibration of the unit). 5. Programming structure of the menu’s

VK-3 6. Calibration of the Unit

This section is necessary so that the unit knows the relationship between the signal of the cell and the weight introduced in the cabin.

There are two ways to calibrate the unit: I) NORMAL CALIBRATION (Valid for all types of load cells). 1) SETTING OF THE ZERO:

a) Situate in the option of menu .

b) Check that the cabin is empty and press the key . The display menu will become intermittent during 10 seconds.

c) Press again the key while is in intermittent the operation will be confirmed with a count-down. And when it finished, the display will present the parameter

Remarks: If you don't press the before finishing the intermittence, the operation will not stored, and the display presents again the parameter .

2) ADJUST OF THE WEIGHT: a) Situate in the option of menu . b) Introduce inside the cabin a well-known weight (It is recommended at least as minimum 50% of the

complete load) & press .

c) Put the value of the weight placed in the cabin using the keys .

d) To save the value press the key 2 times (The unit will start to count -down and the value will be save). Then the display will present the next parameter .

Remarks: If you haven't press the for the 2nd time, the operation will not stored, and the display

presents again the parameter . II) CALIBRATION OF THE CELL FOR DIRECT TRANSMISSION (TCE model) To fulfill this operation it is not necessary to introduce a well-known weight in the cabin

1) SETTING OF THE ZERO (same as the operation of the normal calibration). 2) ADJUST OF THE WEIGHT:

a) Situate in the option of menu .

b) To enter and be able to asigned a value press . c) Put the calibrated value of the cell using this keys . (This data comes at the end of the cables, and it belongs to the calibration value of the manufacturer.)

d) To save the value press the key 2 times(The value stored in the memory).then the display will

present the next parameter .

Remarks: If you haven't press for the 2nd time the operation will not stored, and th display presents again the parameter .

7. Alarms

The alarms are the load levels in which that change the state of the relay. To adjust them it is not necessary any weight, just program them on the key. Value of the load indicating that the elevators is complete. When the content of the elevator overcome this value, the state of the relay change to indicate the complete load, and the cabin display MB-D will light on up to the head of the dummy.

8. Auxiliary Functions

Option of the chain compensation.This option allows to compensate the difference of weight between floor taken place by the chain. To use this option it is necessary to introduce the approximate weight of the chain, keeping in mind that the allowed maximum value is 50kg. In the event of putting it to zero the chain compensation will be annulled. Allows to configure the output of cabin display and the condition of the relay. Config. Display of low consumption Output of cabin display ConF = 0 ON ON Intermittent activation (LED) ConF = 1 ON ON Progressive activation (MB-D) ConF = 2 OFF OFF Intermittent activation (LED) ConF = 3 OFF OFF Progressive activation (MB-D) Key to protect the parameters for possible modifications. Normally the unit comes out from the factory with the key of 0000, that allows a free access to modify the parameters. -In the case of putting another key different from 0000, the access to modify the parameters is protected.(its highly recommended to remember your key)

-If the unit is protected with a key. And once entered in the menu the display presents intermittent to request us the keycode. It is necessary to introduce the key at this time, if we wants to modify some parameter. -To introduce the key, while is in intermittent, press the key and a number will appear that it is necessary to substitute for the correct key.

Remarks: If you don't remind the key that you put on, write down the number that appears and call the supplier, it will indicate you the right key.

9. Mode of low consumption

As the display is the most that consumes and it is not an element that is visible. It has been keep in mind a way of a low consumption, that once the display turns off automatically, the display presents a rotating segment to indicate that it is continuesly working. Cases that the unit enters in the function of low consumption.

1) When connecting the unit to the power supply, it presents the weight during 3 minutes. And in the event of not touching any key, automatically it will pass to the mode of low consumption. 2) When it passed one hour since the last time that having played the key.

3) When the unit is presenting the weight, pressing the key during two seconds

Remarks: To leave the function of low consumption it is necessary to press any key. 10. Electrical Characteristics

To connect properly the sensor to the unit control, please see section No.1 (Installation)

This section is to knows quickly the keys of this unit.

a) To find the parameter that is wanted to change press successively and to accede to the parameter

press

b) Modify using this keys , c) To save the data press 2 times

2. Before to start to calibrate the unit control, please be advise to do the following: a) Down the cabin to the lower plant of the building. (or in the half of the itinerary)

b) Bounce inside the cabin to avoid possible hooks on the guide rail. 3. Most important parameters to calibrate step by step:

1. Set the Zero of the unit with the empty elevators:

- Situate in the parameter

- Press , and will start to count-down.

2. Adjust of the Weight (Peso): - Put a well known weight inside the cabin ( at least 50% of the complete load)

- Introduce in the parameter the value of the load that has been placed in the cabin using this keys

, then to save it press 2 times and the unit will start to count-down.

3. Put in the value of the load, starting from which is required to activate the alarm of complete load. (Example: 100% of the nominal load)

4. Put in the value of the load, starting from which is required to activate the alarm of overload. (Example: 110% of the nominal load) 5. Put in the value of the load, starting from which is required to activate the alarm of auxiliary (In case if your going to use like for example: to activate a buzzer or to detect a minimum load like the weight of a child).

Note: It is important to calibrate the setting of zero before doing the operation of the adjust of weight.
